I've been playing a priest off and on since Vanilla, and I had NO IDEA we had so many cool specs to choose from!
Blood, Assassination, Prot, Elemental, Balance, Feral, Arms, Fire, Beast Mastery, Destruction, Unholy...
I still only see the three old ones. I guess I must be doing it wrong.
OT: I'm reluctantly leveling with a shadow off-spec. Disc is still my main spec, and my shadow off-spec will turn into a holy off-spec once it's time to raid. Versatile healer for great justice!
